rezistencë

Rezistencí is the instrumental singular form of the Czech noun rezistence, which means resistance. The term is used across disciplines to denote opposition to a force, influence, or threat, or the property of withstanding a load or effect. It derives from Latin resistentia and entered Czech via German and other languages. In grammar, rezistencí is used after prepositions that require the instrumental case.

In physics and engineering, resistance describes the opposition to the flow of electric current or to deformation, depending on context. The electrical resistance of a conductor is often described in relation to Ohm’s law, V = IR, with R measured in ohms. In materials science, mechanical or thermal resistance refers to a material’s ability to withstand stresses, heat, or corrosion.

In biology and medicine, rezistence denotes the ability of organisms or cells to withstand drugs or antimicrobial agents. Mechanisms include genetic mutations, gene transfer, and efflux pumps, leading to treatment failures and the need for alternative therapies.

In social and historical contexts, rezistence refers to organized opposition to an occupying power or an oppressive regime, such as wartime resistance movements. The term can also describe nonviolent civic resistance or dissent within a society.

Notes: The instrumental form rezistencí is common in formal Czech prose. Related terms include rezistence and odboj, with usage that varies by field and historical tradition.
